Abstract

Amaç: Premaxillada implant cerrahisi, diş ekstraksiyonu (gömülü ve süpernümere dişler dahil) dahil olmak üzere bir dizi cerrahi operasyon uygulanabilir. Nazopalatin kanalı (NPK), premaxilla'daki en belirgin anatomik oluşumdur. NPK, nazopalatin sinir ve inen nazopalatin arter gibi anatomik yapılar içerir. İmplantın, çevresindeki sinir dokusu ile teması, osseointegrasyonun başarısızlığına ve sinirlere zarar vermeye neden olabilir. Bu çalışmanın amacı, konik ışınlı bilgisayarlı tomografi (KIBT) görüntüleri kullanarak NPK'nin morfolojisini ve morfometrik özelliklerini değerlendirmek ve bu özellikler ve demografik değişkenler arasındaki ilişkiyi incelemektir.
Gereç ve Yöntemler: Yaşları 18 ile 74 arasında değişen, ortalama yaşı 40.15 olan toplam 293 hastanın KIBT görüntüsü incelenmiştir. İstatistiksel analizinde gözlemciiçi korelasyon katsayısı, tanımlayıcı ve frekans istatistikler, ki-kare testi, bağımsız örneklem t testi ve tek yönlü ANOVA testi kullanılmıştır.
Bulgular: Aksiyal, koronal ve sagittal kesitlerde gözlenen en yaygın varyasyonlar sırasıyla tek Stenson foramen, tek NPK ve huni tipi NPK idi. Bu varyasyonlar demografik verilerle istatistiksel olarak anlamlı bir korelasyon göstermemiştir. Bununla birlikte, demografik veriler ve NPK'nin morfometrik ölçümleri arasında istatistiksel olarak anlamlı bir ilişki izlenmiştir.
Sonuçlar: Kısıtlı bir Türk populasyonunu araştıran bu çalışma, NPK'nin dikkate değer bir morfolojik ve morfometrik çeşitlilik yelpazesi sergilediğini vurgulamaktadır. Premaksillada kret augmentasyonu ve implant cerrahisi gibi herhangi bir cerrahi prosedürden önce komplikasyonları önlemek için NPC'nin üç boyutlu bir değerlendirmesinin yapılması önerilmektedir.

Morphometric and Morphological Variations of the Nasopalatine Canal and Their Relationship with Demographic Data

Abstract

Background: A range of surgical procedures may be undertaken in the premaxilla, including implant surgery, tooth extraction (including impacted and supernumerary teeth). The nasopalatine canal (NPC) is the most prominent anatomical formation in the premaxilla. The structure contains anatomic structures, such as nasopalatine nerve and the descending nasopalatine artery. Contact between the implant and surrounding nerve tissue may result in failure of osseointegration and damage to nerves. The objective of this study was to evaluate the morphology and morphometric features of NPC using cone beam computed tomography (CBCT) images and to examine the relationship between these features and demographic variables.
Methods: A total of 293 patients, ranging in age from 18 to 74 years with a mean age of 40.15 years, underwent examination of the nasopalatine canal. Intraobserver correlation coefficient, descriptive, Pearson Chi-Square, Independent t test and One-Way ANOVA tests used to analyze obtained data.
Results: The most prevalent variations observed in the axial, coronal, and sagittal sections were the one Stenson foramen, single canal, and funnel-type NPC, respectively. These variations exhibited no statistically significant correlation with demographic data. However, a statistically significant relationship was identified between the demographic data and the morphometric measurements of NPC.
Conclusions: This study, which investigates a restricted Turkish demographic, highlights that NPC displays a notable spectrum of morphological and morphometric diversities. It is recommended that a three-dimensional assessment of the NPC be conducted in order to prevent complications prior to any surgical procedures in the anterior maxilla, such as local anesthesia and implant surgery.
